DESCRIPTION
The INA122 is a precision instrumentation amplifier
for accurate, low noise differential signal acquisition.
Its two-op-amp design provides excellent performance
with very low quiescent current, and is ideal for
portable instrumentation and data acquisition systems.
The INA122 can be operated with single power sup-
plies from 2.2V to 36V and quiescent current is a mere
60µA. It can also be operated from dual supplies. By
utilizing an input level-shift network, input common-
mode range extends to 0.1V below negative rail (single
supply ground).
A single external resistor sets gain from 5V/V to
10000V/V. Laser trimming provides very low offset
voltage (250µV max), offset voltage drift (3µV/°C
max) and excellent common-mode rejection.
Package options include 8-pin plastic DIP and SO-8
surface-mount packages. Both are specified for the
–40°C to +85°C extended industrial temperature range.

NOTES: (1) Stresses above these ratings may cause permanent damage.
(2) Input terminals are internally diode-clamped to the power supply rails.
Input signals that can exceed the supply rails by more than 0.3V should be
current-limited to 5mA or less.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
